The easy-breezy shoulder-length cut

The bang-accented bob

Long before Gwyneth and other Hollywood hairbots went under the scissors for a cool, chin-length bob, a fresh-faced Renée was sporting the super-sleek look.

Long va-va-voom waves

Retro curls

The cosmopolitan bob

Always one to put a new twist on a classic style, Renée amped up the bob’s chic factor by going blonder, straighter and flirtier than ever before.

The half-up, half-down hairstyle

Unlike her low-key and adorably frumpy character in Bridget Jones, the actress opted for a fancier look: dark hair pulled halfway up in a soft, classy ‘do. Keep this look in mind the next time you prep for a date. “There’s a romantic quality that comes across when hair is half-up, half-down. The woman who wears her hair partially up is playful and sexy but definitely romantic,” says hair guru Ted Gibson.

The sexy redhead

Bye-bye, blondie: In a head-turning auburn bob with blunt bangs, Renée made a bold statement at a New York City bash. To keep hair color like Renée’s shiny and bright—and touch-up appointments with your colorist to a minimum—wash two to three times weekly with special antifade shampoos and conditioners like those from Redken’s Color Stay line.

Side-swept curls

Looking like she stepped out of a fairy tale herself, Renée was picture-perfect at the Cinderella Man premiere thanks to her golden-blond hair and wispy bangs. If you make a big hair-color change like Renée’s, remember to use intense conditioners like Pureology NanoWorks Hair Masque after switching shades, as color treatments can make hair dry and brittle.

The sleek, side-parted ‘do

She may have played a prim-and-proper children’s-book author in Miss Potter, but when she turned up at the Late Show With David Letterman to promote the film, Renée flaunted a long, seductive new ‘do.

The curly updo

While she wasn’t up for a nom (this year, anyway), Renée held her own at the 66th Annual Golden Globe Awards in Beverly Hills sporting a much-talked-about dress and a daring hairstyle to match. The major volume and curls in this updo are the perfect complement to her megawatt smile.
